abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
in present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. a double active sites model for ziegler-natta catalysts is used for simulation of polymerization reaction. hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with differentiall...
objective: in this study efficacy of sub lingual misoprostol was examined in comparison to oxytocin (i.v.) for inducing of labor in term pregnancy. materials and methods: seventy patients were allocated by blocked randomization to groups a (n=35, sub lingual misoprostol 25 μg four hourly to maximum of 5 doses) and b (n=35, continuous oxytocin infusion). results: delivery active phase and total ...
it is well established that the active continuous recovery is preferred to passive recovery. but the active period of this recovery is long (20-60 minutes) and the intensity is not controlled. furthermore, most severe trial exercises need short-term active recovery for better performance so that the athletes can return more rapidly to their normal state and more desirable performance. however, ...
labor pain is one of the most tiresome types of pain. so human has been seeking to allay this pain until now. administration of a suitable agent such as entonox during labor is very beneficial for childbirth outcomes. entonox can be administered in two ways: intermittently and continuously. the aim of this study is to demonstrate whether continuous method is as safe as intermittent method? this...
امروزه در تولید تصویر های هوایی و ماهواره ای و دیگر داده هایی چون لیدار و نظیر آن نسبت به گذشته سرعت و تسهیل وجود دارد که این امر تولید نقشه های کاربری و طبقه بندی های مورد نیاز برای اهداف مربوطه را با سهولت بیشتری ممکن می سازد. علوم فتوگرامتری و سنجش از دور با پیشرفت هایی که در سال های اخیر در زمینه شناسایی و استخراج عوارض داشته اند نقش بزرگی در زمینه تولید داده های مکانی و نیز تأمین و بروز رس...
cytotoxicity evaluation of daphne mucronata (thymelaeaceae) extract and one of its active purified components, using seven different cancerous cell lines, revealed the strong antiproliferative activity of the plant. using flow cytometry technique, it was found that treatment of the most responsive cells (k562) with the plant extract or the active component inhibited the progression of cells thr...
the purpose of this study was to examine the english language needs of medical students at tehran university of medical sciences . analysis of the needs took place for three groups: 320 undergraduate students, 30 postgraduate students and 20 university instructors. a triangulation approach to collect data was used in which a combination of the quantitative (using the questionnaires) and qualita...
Introduction: The formalin test is the most accepted chemical test for evaluation of nociception. It requires the injection of an adequate amount of formalin into the surface of the hindpaw. Formalin test consists of phase 1 (0-7 min) and phase 2 (15-60) in which the animal shows painful behaviors. These phases are separated with a quiet phase named interphase, in which the nociceptive respon...
BACKGROUND Interventions given to women admitted in latent or active phase of labor may influence the outcomes of labor and ameliorate complications which can affect the mother and fetus. Labour management, maternal and fetal outcomes among low risk women presenting both in latent phase and active phase of labour in Tanzania have not recently been explored. METHODS This was a descriptive cros...
